CRESTA is a built-in self-repair analyzer (BISRA) used for repair of bit-oriented memories, which can repair all repairable bit-oriented memories with available spare resource. This paper enhances CRESTA to support embedded word-oriented memories. Within each read cycle of at-speed memory BIST, the analyzer is able to handle multiple-bit failure in a word-oriented memory. Furthermore, to reduce area overhead, the proposed analyzer is reconfigurable to process all repair strategies in serial. To cover all repair strategies efficiently, we propose a branch and bound algorithm to select repair strategies.
